Lodash is a modern JavaScript utility library delivering modularity, performance, and extras. It includes a `forOwn` method that provides similar functionality to the for-own package, but with additional features and optimizations.

underscore

Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects. It includes a `_.each` method that can be used to iterate over object properties, similar to for-own.
